Klopp was also able to offer good news on the only possible downsides on the day for Liverpool, the halftime removal of Xherdan Shaqiri and the second-half substitution of Virgil van Dijk, who left the pitch clutching his ribs.

Klopp revealed Shaqiri’s early substitution in his first Liverpool start was purely tactical despite his involvement in the build-up to the first goal.

His shot hit Shane Long before going in off Hoedt, and later, his superb 25-yard free kick against the bar, which led to Salah’s tap-in for the third.

“I said to Shaq at halftime that I’d never taken a player off at halftime after such an influential half,” Klopp said.

“He was not injured, but I wanted to control the game, go back to our normal formation, and that helped us.”

The Swiss international understood the decision, according to his manager.

“He’s a fantastic boy, so there was no problem. I explained it to him, usually I don’t explain substitutions, but I thought today it made a bit of sense,” Klopp added.

“It’s just good to have him. You saw the free kick, it was outstanding. What a ball!”

Van Dijk, said Klopp, aggravated bruised ribs which he carried into the PSG game in midweek. “He had already before the PSG game kind of a bruised rib, which is very uncomfortable, and today he got another hit there,” he said.

“It’s not cool, but should not be too serious. He said he couldn’t shout any more, so that’s obviously 60 percent less of his level!”

Klopp’s 600th competitive game as a manager saw Liverpool extend an impressive home league record, unbeaten now in 18 games and 17 months at Anfield.

No opposing player has even scored here in the league since February, with Liverpool scoring 23 in the same period.

While the Saints enjoyed some promising moments they could not find the cutting edge to worry their opponents.

The second half was rather a non-event, with Salah’s disallowed finish after James Milner’s shot was cleared off the line the closest Liverpool came to adding gloss to the scoreline.

The victory ended a positive week for Liverpool with a third win after a statement victory against top-four rivals Spurs at Wembley last weekend and the breathless, late victory against Paris Saint-Germain in the Champions League.
